Embodiment approach 1
[0024]
[0025] The coating composition of this embodiment contains a fluorine oil, a fluorine-based solvent, a fluorine resin, and scaly particles.
[0026] The fluorine oil contained in the coating composition of this embodiment is a liquid immiscible with water, vegetable oil, and hydrocarbon oil, and if mixed with a fluororesin, it will not be separated but mixed at the molecular level. When the contained fluorine-based solvent evaporates, a gel with lost fluidity can be formed. The gel (gel-like) here is preferably a non-fluid state in which a fluororesin and a fluoro oil are homogeneously mixed at a molecular level, but may be in a slightly phase-separated state. From the viewpoint of maintaining the lubricity to the oil for a long period of time, it is preferable to use a fluorine oil with a low evaporation rate. The evaporation rate here refers to the mass loss ratio when the fluorine oil is applied to a flat plate to form a film thickness of about several μm and th...
Embodiment approach 2
[0055] In Embodiment 2, an embodiment in which a paint film is multilayered by forming a lower layer between the paint film and the base material described in Embodiment 1 will be described. like image 3As shown, the lower layer 6 is formed on the substrate 1 , and the paint film 2 described in Embodiment 1 is formed as an upper layer on the lower layer 6 . The lower layer 6 is a non-fluid gel in which a fluorine oil and a fluororesin containing 1% by mass to 100% by mass of the fluorine oil are mixed at the molecular level. In the multi-layer coating film that is made of upper layer (paint film 2) and lower layer 6, because lower layer 6 does not contain scaly particle 3, so can increase the content of the fluorine oil in lower layer 6 compared with upper layer, or by making upper layer The film thickness of the film is reduced to increase the orientation of the scaly particles 3, or to increase the content of the scaly particles 3 in the upper layer, so that the evaporatio...
Embodiment approach 3
[0058] In Embodiment 3, an article to which the paint film described in Embodiments 1 and 2 is applied will be described. Figure 4 and Figure 5 It is a figure which shows an example of the article which the paint film which concerns on Embodiment 1 and 2 is formed in the surface of a base material.
[0059] Figure 4 It is a spindle motor that is a part of machine tools used for metal cutting and the like. The motor 7 is installed inside a cylindrical frame 8 , and a plurality of air passages 9 for air cooling exist in the frame 8 . In order to air-cool the motor 7, the fan 10 provided on the upper part of the frame 8 is designed to operate, and the air is exhausted from the fan cover 11 through the air passage 9 for air cooling.
[0060] During operation, oil mist of cutting oil adheres to air passage 9 for air cooling, fan 10 and fan cover 11 . Therefore, by forming the paint film according to Embodiments 1 and 2 on the inner wall of air passage 9 for air cooling, the ...
